With no menu items the mbr_bootsel code will wait for the timeout (default
10 seconds) and then boot the default device - usually the active partition.
Forcing the 'active' partition was wrong - jmmv has a system which needs
to boot from hd1 where hd0 has no mbr partition info.
I suspect the problem I though rev 1.7 fixed was actually caused by
disklabel copying sector zero of the disk to sector zero of the partition!
Gains another 9 bytes of free space, mbr_bootsel now has 20 free bytes.
- decrement uvmexp.anonpages as it's no longer an anon page.
- null out anon->u.an_page as the anon no longer own the page.
uvm_anfree: add related assertions.
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
Rework logic of gz_{un}compress to make it much less likely to leak fds
(at least 2 non-error paths leaked them!)
Make -S ".xyz" and -S "" both do something sensible.
Make in-situ compression work - only lose the file on error.
Pass an open fd to zopen (renamed zdopen) to avoid fd leakage (was badly borked)
Write header into first 64k output block to writes are aligned.
(more efficient and might avoid some problem with code that doesn't
like receiving partial buffers)
Check file size on compression - double checks against fs full.
Remove some pointless casts, and otherwise simplify some logic.
internally (shouldn't make a difference for callers)
-add convenience macros for config_found() and config_search() to
ease the case where just an interface attribute is specified
the diffs and possibly install the new version of file.
(Based on sshd_config munging code in do_ssh())
* Use modify_file() in do_hosts() and do_ssh().
* Be more specific in do_x11() about what needs to occur.
(This could still be improved).
* Minor sh cleanups. ("sh is not C")
- Clean up the namespace of this module and enable the encode/decode
functions and printing functions.
- Move the code that actually generates the UUID out of the system call
routine and into its own function.
